Lincoln LS Audio

My 2000 LS V8 with approximately 42000 mi has a radio noise problem. In addition to the station I've tuned in or CD I'm playing the speakers are transmitting the sound of the spark plugs firing. When you rev up the engine you can actually hear it through the speaker system. (When the engine is off radio plays beautifully.) I evidently have a radio frequency (RF) shielding problem. Has anyone else experienced this and do you know what was repaired/replaced to cure the problem? Was it near the antenna or near the radio?

    I have the same problem. Not only is it intermittent but it comes and goes when I hit bumps! I've had it in to the dealer 4 or 5 times. The first problem was getting it to occur when the dealer had the car. Then they replaced the amp twice. It's still there and they can't fix it. I also have a new problem. I get static on the radio at the high and low end of the FM band when I turn the rear window defroster on.

    Have the dealer check for TSBs on faulty ground connections.

    You don't say, but I'm guessing you've got the Alpine upgrade (with the subwoofers). I've had the same problem, once under warranty and once right now.

    It certainly has all the earmarks of a bad ground and/or internal connection, given the way it comes & goes when hitting bumps. The wizard who "repaired" it under warranty replaced the subwoofer amp, and it did go away. . .for awhile.

    Last summer, as I was rolling south through Nevada listening to a book on tape, it reappeared. In the ensuing months, I've learned that the single best way to make it go away (for up to a week) is to open the trunk & give the subwoofer amplifier a sharp rap with my hand. So far, it's worked every time. . .for awhile.

    I'm not sure what's in the Service Bulletin, but over the break next week I intend to have a careful look at how the amp is mounted & whether star washers and/or a grounding strap might be in order.

    After all, I don't want this "issue" to appear while I'm trying to sell my poor orphaned LS, which I'm hoping to do in the next ~year. It may only be worth $1.87, but if the audio system goes South during the test drive. . .
  • I have a 00 LS V8 with 80K. This problem sounds similar to one recently posted by someone saying their radio was playing the spark plug firing. I just had my car in to replace the sway bar and bushings. In the process, I had them replace the battery. Ever since then, I have gotten the weird feedback from the radio. I took it back in and they couldn't find anything, in fact in the process of their inquiry, the sound went away. Since then, a week has passed and it has come and gone. If I disconnect the amp for the subwoofers, the sound is gone, but then no bass. Otherwise the radio works fine. Could this be something with the battery, or the way its hooked up? Any suggestions would be appreciated!!

    Recheck the battery cables and all connections in the trunk area. Sounds like a loose ground.

    You mean the rapid "Tick, Tick, Tick...." noises?

    My dealer replaced my radio (under warranty)quoting "electrical problems".

    Funny thing?
    Some times my stereo lights stop working on the new stereo.

    I had the same problem on my 00 LS. The problem is ignition noise being induced on the 12VDC supply to the speaker power amp mounted under the rear deck. I placed a 200 picofarad capacitor accross the supply at the connect to this amp this and it fixed it.

    Correction - the capacitor I used accross the supply was a 200 micofarad capacitor

    hey guys, having some problems from factory stereo in 01. Just bought it with 72k, and doing since test drive. The sound system has this crazy reverb, echo sound...Played with all the settings and cant change something wrong???

    Please help if you can.

    It's a DSP mode. Check the owner's manual for specific instructions on changing it.
  • I recently installed a used factory 6 Disc Alpine Radio CD Changer in my 2000 LS. Radio works fine but having problems with the CD player.Can not get the CD tray to open to load a cd. If I hit the eject button the 6 cd circles blink for which one to select. As soon as you select a #, it says CD error. Tried hitting the load button and that says slots full. I can not get the tray to open. Anyone have any ideas?
  • I am having the exact same problem with the Alpine CD player in my 2002 Lincoln LS. Have you figured out they problem yet or have you had any answers to your questions?
  • I know you posted this last year-- my LS is doing same thing... it almost sounds like there is no bass... is that what yours sounded like? did the DPS change fix the problem?

  • akirbyakirby Posts: 7,622
    Mine didn't do it. If it's not the DSP settings then the subwoofer amp may have gone out.
  • I was wondering if anyone has instructions on how to replace the rear deck speakers on an 02 LS with the Audiophile System. Any help will be greatly appreciated

    The automatic lighting system for my alpine stereo in my 2001 Lincoln town Car does not work correctly. Normally only the display lights up. The lights for the controls come on from time-to-time but not as they should. Any ideas on a fix??
  • My speakers have absolutely no base in my 2000 ls, i have the alpine factory speakers any ideas?
  • akirbyakirby Posts: 7,622
    Replacing the factory speakers will help. Infinity or Polk Audio are good choices. 5x7s.

    Same thing happened to mine. You have to replace the head unit. I found one on Ebay for $50 shipped.
